APPARATUS FOR IVIAKINGVPA|YLS FROM PULP.

SPECIFICATION forming part of Letters Patent No. 658,851, dated October2, 1900. Application iled June 26, 1899.1 Serial No. 721,932. (Nomodel.)

To all whom it may concern:

Be it known that I, FRANK EUGENE KEYES,

a resident of New York city, in the countyof New York and State of NewYork, have in- 5 vented certainnew and useful Improvements in Apparatusforl Making Pails from Pulp; and I do hereby declare the following t'obe a full, clear, and exact description of the invention, such as Vwillenable others skilled in the 1o art to which it appertains to make anduse the and every part of which shall be subjected to.

the same degree of pressure.

A further object is to provide a pail-makz5 ing machine which will beextremely simple in construction, cheap to manufacture, easy to operate,and most effectually perform the functions for which it is intended.

With these objects in view the invention 3o consists in certain novelfeatures of construction and combinations and arrangements of parts, aswill be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure' 1 is 35 a view in sectionillustrating my improvements. Fig. 2is a plan view with the top removed,and Figs. 3, 4, and 5 are sectional views oldet-a-ils of construction.

A represents a series of uprights or supports, on the upper ends ofwhich a ring 1 is secured. A series of brackets 2 are spaced apart andsecured on the ring l by means of pins or bolts 3. The brackets 2comprise parallel uprights 4 4, having alined holes or open- 45 ings forthe free passage of threaded rods 5.

A gear wheel 6, having a central screwthreaded hole, is mounted on eachrod 5 between the upright sections 4, and a cap or wardly-projectingarms 12, the free ends of which are adapted to move in guides in theuprights A. Each arm 12 is provided with a. recess 13 for the receptionof a ring 14. A 65 series of blocks l5 depend from the ring 1 and areprovided with recesses 16 for the ac commodation of the ring 14, andthelatter is made with recesses 17a to permit the base 9 to pass the blocks15, and it will be seen that 7o when the base 9 is in its highestposition the ring 14 can be turned to throw the recesses 17a out ofalinement with the blocks 15, and hence lock the base in place. Agrooved and perforated mold 17 is secured on the top of 75 the base 9.The mold 17 is just the shape of theinside contour of the pail to bemade and is provided around its lower edge with a peripheral flange 18,on which a ring 19 is disposed. The ring 19 is adapted to secure acovering 20, of canvas or other fabric,over the mold, and said mold isperforated throughout its entire body for the escape of moisture,

as'will be more fully hereinafter explained.

vof the band 23, and a sleeve 27 is secured in 95 the cap and isdisposed against the band 23 at its upper edge andY assists in holdingsaid band in place. The lower edge of the band 23 is held in a groove 29in the ring 1 by means of a ring 30, havinga flange 3l thereon toinclose the lower edge of said band.

A chime-plate 32 is movably mounted in IOO the sleeve 27 and is providedcentrally on its upper face with a socketed enlargement 33, in which ascrew-threaded rod 34 is secured by means of a pin 35, passing throughholes in the enlargement and rod, as shown. A gearwheel (l is disposedin the cap and mounted on the rod 34, said gear-wheel being connectedwith the shaft c and adapted to be turned thereby.

The shaft c is provided with a bevel-gear e, which meshes with abevel-gearf, secured on a vertical shaft g. The shaft g has also securedthereon a gear-wheel h, which meshes with an idle gear t, and the lattertransmits motion to the gear d, as clearly shown in Fig. 3, so that theshaft c is adapted when turned to transmit motion through the gearingheretofore described to simultaneously operate the staves andchime-plate.

The chime-plate 32 is provided around its edge with a chamber 3G, thebottom of which is perforated to permit the moisture pressed from thepulp to entersaid chamber 36. Drainpipes 37 communicale with the chamber36 and are adapted to carry od the moisture from said chamber.

The chime-plate 32 is provided with a hole or opening 33, and apulp-inlet pipe 39 communicates with said opening and is provided with aperipheral flange 40, disposed against the top of the chime-plate. Aplug or valve 4]. is disposed in the pipe 39 and is adapted to close theopening 38 to prevent the passage of pulp into the machine. The plug orvalve 4l is made ou its upper end with a rectangular casing 42, whichprojects laterally therefrom, and wilhin said casing a cam 43 isdisposed. The cam -L3 is secured on the end of a shaft JA, and saidshaft is provided with a suitable means (not shown) for turning the sameto raise and lower the valve or plug 4l.

The operal ion of my improved apparatus is as follows: When a pail is tobe formed, the valve il is raised and the proper amount of pulppermitted to flow through the chimeplate into the space surrounding themold, when the valve 4l will be closed. The rack a is now operated toturn the gears 6 and CZ to press the plungers 2l inward against therubber band 23. The gear d forces the chimeplate downward, and saidchime-plate and plungers press the pulp into shape around the mold, themoisture escaping through the perforations in the mold and the pipe 1l.When the pulp has been sufficiently pressed, the ring li is turned so asto bring the recessses therein in alinement with the blocks 15 and theplungers are withdrawn partially and the base-plate 9 lowered. When thebase-plate and mold are free from the main portion of the apparatus, themolded pail can be readily removed and the parts moved to their formerposition and the operation repeated.

By the use of the heavy rubber band the pressure will be uniformthroughout the walls of the pail, the pulp composing the walls of thepail will have a uniform density and thickness in every part, so thatthe waterproofing material to which the pail will he treated willpenetrate the walls to the same depth throughout, and no stave marks orridges will appear on lthe pail, as is the case with pails manufacturedin machines as heretofore constructed.

Various slight changes might be resorted to in the general form andarrangement of the several parts described without departing from thespirit and scope of my invention, and hence I would have it understoodthat I do not wish to limit myself to the precise details set forth, butconsider myself at liberty to make such slight changes and alterationsas fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- l. In an apparatus for making pails frompulp, the combination with aperforated mold, of a fiexible band aroundsaid mold and spaced therefrom, plungers or staves adapted to press saidflexible band toward said mold and a chime-plate adapted to be pressedtoward the end of said mold.

2 In an apparatus for making pails, the combination with a perforatedmold, of a fabric covering for said mold, a flexible band around themold and spaced therefrom and plungers or staves adapted to press saidflexible band toward the mold.

3. In an apparatus for making pails from pulp, the combination with aring and a movable base, of a perforated mold on said base, a movablenotched ring carried by the movable base, recessed arms on the fixedring for the reception of said movable ring for locking said base in itshighest position, a flexible hand around said mold when the latter is inits highest position, means for pressing said flexible hand toward themold, a chimeplate and means for pressing said chime-plate down towardthe top of the mold.

In testimony whereof I have signed this specication in the presence oftwo subscribing witnesses.

FRANK EUGENE KEYES.
